File system

I downloaded an mp3 from the Internet on the phone and wanted to use it as a notification sound. I moved the file using File Expert from the Downloads directory to the Notifications directory and it shows that the file moved there. I couldn't see the file in the Notification sounds list and when I plugged the phone into the computer and browsed to the Notifications folder, the file wasn't there but rather still in the Downloads directory. Is there no way to actually move files using a file manager on the phone itself?

Astro seems to be having issues with ICS as I can't see the toolbar. The buttons function but since I can't see them, I can't really use them. I haven't rooted and I haven't checked permissions on that directory yet, but once I'm connected to USB I can move the file from within Windows and the file shows up in the notifications list.

Edit: I just checked and I do have R/W permissions on that folder when checked with Astro. Haven't found a way to see those details in File Expert though.
